Multiplayer not working – Server issues?

[Glenn Quagmire]

Hi everyone,

My brother and I have been playing multiplayer in Knights of Honor II: Sovereign without any issues until this morning (around 8 AM). Yesterday, we had to disable IPv6 to get it working (on Steam Deck, there were no problems).

Today, however, we can’t even press the multiplayer button due to server issues. Is there an update being rolled out, or are the servers down for maintenance? Any official info on this?

Thanks in advance!

same here, waiting fix.

The game has major issues, Multiplayer hasn't been working since late January 2025.
*Some* people say they can get it to work by crippling their network connectivity (disable IPV6) but this is far from a universal or good fix.

I wouldn't hold my breath for a fix, get a refund under your local consumer protections and select something else to play while you wait.. if they fix comes you can always rebuy.

Use this to check the ipv6.

I got mp working fine with this, but tweaked :

import socket, sys

def ipv6_server(ip, port):
with socket.socket(socket.AF_INET6, socket.SOCK_STREAM) as server:
server.bind((ip, port))
server.listen(1)
print(f"Server listening on [{ip}]:{port}...")
conn, addr = server.accept()
print(f"Connected by {addr}")
conn.sendall(b"Welcome to the IPv6 server!")
conn.close()

def ipv6_client(ip, port):
with socket.socket(socket.AF_INET6, socket.SOCK_STREAM) as client:
client.connect((ip, port))
print(f"Connected to [{ip}]:{port}")

if len(sys.argv) != 4:
print("Usage: python script.py <mode> <ip> <port>")
else:
mode, ip, port = sys.argv[1], sys.argv[2], int(sys.argv[3])
ipv6_server(ip, port) if mode == "server" else ipv6_client(ip, port)

Is this via the .cfg?
Shocking that the devs couldn't push this out as a couple kb patch.. I believe I suggested they do something similar weeks ago.

Go to store page and report the game as broken and list the issue. With enough reports steam will remove the MP tag from the store page to prevent other people from getting mislead into buying a product that isn't as advertised.
